FLUID-CONTROLLER? ELECTRIC REGULATOR. v

Specification of Letters Patent.

Patented Dec.. M T915.

To all whom t may concern:

Be it known that I, EDWARD V. ANDERSON, a citizen of the Uni-ted States, residing at Monessen, in the State of Pennsylvania, have invented certain new and useful 'mprorenients in Fluid-Controlled Electric Regulators, et which the following is a speciication.

My invention relates generally to attachments for stopping andstarting an electric motor, or otherwise controlling a circuit by change of pressure in a fluid container. Its primary object is to provide certain and simple means to open and close an electric circuit whereby to maintain the level of liquid or the pressure of iiuld in a tank hetween fixed maximum and minimum limits, and to make the action ot' such attachments adjustable and more sensitive as well as more positive. This and other objects are attained by means of apparatus of which show an example in the drawings, wherein- Figure l is a rear elevation and partial vertical section of the apparatus showing the operating,` parts inside; Fig. 2 is a plan oi the eperatin@` means 'for throwing the electric switch; and Fig. 3 is an end View of the upper part of the mechanism, from the ulate the pressure necessary to Ceperate tl left in ,if

ln my apparatus, the casing yrniing a pressure chamber has connection l to an f tank in which fluid level or pressure is to he controlled. The chanil'ier (2) heneath a closed diaphragm which divides the casing transversely. 'rle the upper side of this diaphragm is attached a stein Li; bolts 5, 5, 'fastened te the casing; and threaded at the other end., carry a guiding plate 8 coniining coil springs 6, 6., which are placed around the stern l with their louer ends hearing against the diaphragm lt may be adjusted in position by nuts i", Tf', to

,more fluid pressure.overcomes the spri that it is free to roll from end te end theren 1n except as it is 'retarded at either end hy the set-screws 12', inserted. in the betteln of the cylinder te normally retain the ball until the desired slant of the cylinder is attained, so that the ball once started rolls rapidly. Slldably, mounted on the cylinder.

running the full length thereof is s 13, which bears, adjustalaly mounted near its ends, rigid studs M, 14', which through slots l5, 15, through the cylinder. Near the middle of this bar 13, and adjust'.u ably mounted thereon, are two rigid studs 1G, 16. Gn one fork ef the supporting arm. l0 is mounted a nozrconducting plate if?, to Which are fixed posts l@ and lil connected to the termini ot an electric circuit threugh the motor or ether a0 aratus to loe started and stopped.A Pirata y mounted on the post 18 and in goed electrical Contact with it is a switch-lever 2O which carries a nen-conducting arm 2l extending upward between etude 16 and 16 of the har 13., The sii-"tch le er 20 has a copper spring 22 te slip over contact washer 23 en the post 1* -as is in switches.

A, pipe running from a tari, my apparatus .at-inlet l, the operatien is follows: Huid enters the chamber (2) its pressure is exerted upward on the phragfin 3. The pressure o' springs 6., opposed tr` the tluid pressure on the disN phragnl deterzrnnes the con tank, by adj'listingn their c inpression means of nuts 7, i. on belts 5, 5', any de sired pressure ot' iiuid in the tanlr is d as the point which equalizes the pressu e en the tue sides of the diaphragm.

the stein is pushed upward. the lett end of the cylinder the f force ol" (lraifity rolls over the set and inward the other end and stud it. extending; across its path des the b 13 in its loose mc" stud l@ acting' en lever 2l. throws 4siyitch 2 out oil engagement with contact 2?, thei breaking the circuit and shutting' @if the ter pump, er ringing* a bell, etc. fis scf iuid is drawn from the tank so that t pressure cf the springs exceeds that cf t c fluid in the chamber (2) the stein is pushed down, the cylinder is tilted in the opposite direction and as it `casses the horizontal pc sitionthe ball rolls to the other end, strikes 'stud 14, slides the bar to the right, and

' Having thus described my invention and illustrated its use, l claim:

l. An electric regulator .switch comprising a motor element, .a fixed electrode, a movable` electrode, a slotted rocking cyhnder containing a rolling ball and attached to be tilted by said motor element, and eonnections to the moving electrode including a rod and a finger projectingV through the slots of the cylinder into the path of the rolling ball whereby th-e switch is closed by the impact of the rolling ball when the cylinder is ltilted.

2. ln an electric regulator, the combimu tion with a motor element, of a pivotally mounted slotted cylinder, an eceentrically pivoted connection oit said motor element to the cylinder, a ball in the cylinder, a sliding rod mounted on the cylinder and having rigid studs projecting through the slots into the path of the ball in the cylinder, and an electric switch operated by the reciprocation of said rod whereby the switch is closed suddenly by impact of the ball on one of the studs after the ball has traversed the length of the cylinder.

3. ln au electric regulator, in combination with a reciprocating motor element, an electric switch operating device comprising a rocking ,slotted cylinder moved by recip` rocation ot said motor element, said cylinder containing' a rolling ball and adjustable means to temporarily retard it at the higher end as the cylinder rocks, an electric switch and a rod attached to the switch and having a stud standingin the path of the rolling ball whereby the switch is suddenly moved by the impact of the hall as it rolls in the cylinder, substantiallyl .is described.

Jr; An electric switch comprising;l a motor element adjustable in amount ot' motion, a 55 pivotally mounted slotted cylinder attached to and rocked by said motor element, a roll ing ball in the cylinder, a reciprocating; rod mounted on the cylinder and having; adjustable studs extending` through said .slots into G0 the path of the ball, a switch closing arm pivotally attached to said rod and coperat ing with another electrode, whereby the rolling' ball by impact suddenly moves said rod both to open and close the electric'mv'itch and the range of movement of the motor clement necessary to operate the switch is adjustable.

In' testimony whereof l have hereunto signed my name in the subscribed witnesses.
